Question 5

Sinoatrial Block (exit block)

Answer 5

SA node fires as normal but impulse is blocked
Resulting in an absent PQRST
P-P interval will march out

Question 6

Sinus Pause

Answer 6

Delay in the impulse from the SA node
Longer P-P interval
Does NOT march out

Question 7

Sinus Arrest

Answer 7

SA node stop firing

Greater than 3x the P-P interval
